An advantage of ERW pipe is that no fusion metals are used and the weld seam cannot be seen or felt. Thats opposed to double submerged arc welding (DSAW), which leaves behind an obvious weld bead that must then be eliminated depending on the application. Welded pipe manufacturing techniques have improved over the years.

Seamless pipes use to be the only choice for lining pipes inside drilling well, but as the worldwide acknowledgement of ERW pipes high-quality weld seam and the cost-effective, more and more projects have been choosing ERW instead of seamless pipe.
Introduction to Welded Pipe Manufacturing - The Process Jul 26, 2018 · Several Electric Resistance Welding (ERW) processes are available for pipe production. The two main types of ERW are:High Frequency Welding; Rotary Contact Wheel Welding. High Frequency Welding. Initially ERW manufacturing process used low frequency A.C. current to heat the edges. This low frequency process was used from the 1920s until 1970.

Types and process of welding pipe-ERW,LW,CW,SAW pipes ERW including high frequency welded steel pipe(HFW) and low frequency welded steel pipe(LFW).Over time, the welds of low frequency ERW pipe was found to be susceptible to selective seam corrosion,hook cracks,and inadequate bonding of the seams,so low frequency ERW is no longer used to manufacture pipe.The high frequency process is still being used to manufacture pipe for use in new pipeline
In contrast to the ERW pipes, seamless pipes, without the seam or the welding line, is able to maintain a uniform shape and great strength under high pressure, temperature or heavy loads. Advantages of ERW pipe and seamless pipe. Seamless pipe owns three unique advantages, namely high pressure endurance, great strength and uniformity of structure.
